Annual Study for Serum Collection for Immunogenicity and Safety Evaluation in Healthy Children Receiving Fluzone®
Annual Study for Serum Collection and Evaluation of Safety and Immunogenicity Among Healthy Children Receiving Fluzone® Influenza Virus Vaccine (2008-2009 Formulation)
Primary Objective:
To provide the Center for Biologics Evaluation and Research (CBER) with sera collected from healthy children receiving the 2008-2009 formulation of the inactivated, split-virion influenza vaccine Fluzone® for further study.
Observational Objectives:
To describe the safety of the 2008-2009 pediatric formulation of Fluzone® vaccine, administered in a one- or two-dose schedule in accordance with Advisory Committee on Immunization Practices (ACIP) recommendations, in children ≥ 6 months to < 5 years of age.
To describe the immunogenicity of the 2008-2009 pediatric formulation of Fluzone® vaccine, administered in a one- or two-dose schedule in accordance with ACIP recommendations, in children ≥ 6 months to < 5 years of age.

Description
Inclusion Criteria:
- Participant is ≥ 6 months to < 5 years of age.
- Participant is considered to be in good health on the basis of reported medical history and a limited history-directed physical examination.
- Parent/legal acceptable representative is willing and able to bring the subject to the scheduled visits and to comply with the study procedures during the entire duration of the study.
- Parent/legal acceptable representative is willing and able to provide informed consent.
- Subject was born at full term of pregnancy (≥ 37 weeks) with a birth weight ≥ 2.5 kg (5.5 lbs).
Exclusion Criteria:
- Reported allergy to egg proteins, chicken proteins, or any other constituent of the vaccine.
- History of severe adverse event to any influenza vaccine.
- Laboratory-confirmed influenza infection or vaccination against influenza in the 6 months preceding enrollment in the study.
- Any vaccination scheduled between Visit 1 and Visit 2.
- Planned participation in any other interventional clinical trial during participation in the study.
- Known or suspected impairment of immunologic function or receipt of immunosuppressive therapy or immunoglobulin since birth.
- Personal or immediate family history of congenital immune deficiency.
- Developmental delay, neurologic disorder, or seizure disorder.
- Chronic medical, congenital, or developmental disorder.
- Known Human immunodeficiency virus (HIV)-positive mother.
- Prior personal history of Guillain-Barré syndrome.
- Any condition which, in the opinion of the Investigator, would pose a health risk to the subject or interfere with the evaluation of the vaccine.
- Thrombocytopenia or bleeding disorder contraindicating intramuscular (IM) vaccination.
